[wasm][coreclr] pinvoke and internal calls generator

[radekdoulik]

We will reuse the generator from Mono, so it will be compile time solution with generated C sources

• port the generator task from Mono
  • interp to native [wasm][coreclr] First part of the call generator, interp to native #121491
  • reverse pinvoke [wasm][coreclr] 2nd part of call helpers generator, reverse calls #122007
  • pinvoke
• use it for runtime build
  • interp to native [wasm][coreclr] Extract call helpers to separate source file #120944
  • reverse pinvoke
  • pinvoke
  • check for changes after libs build and request manual update when needed
• use it for app build
• UMCO support in coreclr Add support in WASM for calling UnmanagedCallersOnly functions #121359
• make pinvoke callls work in the Interpreter tests
• detect collisions in reverse table
• PInvoke address class feedback - consider using record or improve comparison
